With the pregnant actress perhaps craving fish, or at least something salty and fried, the expectant couple stopped by Cuz's Fish Shack in Bridgetown for lunch. The cheerfully painted eatery boasts a surfer-friendly vibe and purports to offer up the best fish sandwich (or "fish cutter") on the island.

Bilson, clad in a white tanktop and bright tribal-print shorts, showed off just a hint of a baby bump as she chowed down on a sandwich garnished with lettuce and tomato and sipped an orange soda.

Who else is hungry?!

Bilson and Christensen jetted to the Caribbean within days after news of her pregnancy first broke. The Hart of Dixie star had started to talk more regularly in interviews about her desire to have children, so the shock value was low when E! News learned that a baby was on the way.

"To start a family would be good, any year in the next few years," she divulged in the June issue of Health, which featured Bilson showing off her fit frame on the cover. "I've always wanted to be a mom. I have always wanted kids. I can just see this little toddler waddling around the house."
